W/TNESSES cally about their lhorizontal one end secured to the stub tongue 1 near the forward end, by means of bolts 7, is outwardly oilset, and secured near the opposite end of the stub tongue by means of belts S, the end of the bar beyond the bolts 8 being laterally disposed substantially parallel to the vehicle. A second bar 9 has an end scoured to a flat portion 1U of the bar 6 at the point where it is offset from the stub tongue 1, and has an opposite end secured to the end of the. bar 6 by means` of a rivet 11 and extending therebeyond` pivoted in a bracket 12 carried by the vehicle 3 by means of a bolt 13. The bar 9 is secured to the art lO'of the bar 6 by means of rivets 14 and ms the extremity formed into a bearing 15. A pivot pin 16 is arranged in the bearing 15 and carries a bracket 17. The bracket 17 is pivotally arranged in a recess 19 of the guide. tongue 18 and is secured in position by mea-ns of a pivot pin 20. The guide tongue 18 is arranged at an angle with the stub tongue 1 and normally lies in the line of draft of the vehicle. The stub tongue and the brace can swing vertipivots.

A socket 21, haviinr an inclined upper face presenting a lateral ange 22, is\secured at the underside of the stub tongue 1, near the free end of the same, by means of bolt-s '.23 passing through suitable. openings in the tlange 22. The. socket 21 has a suitable opening or hole. 24 for a purpose which will appear hereinafter, and strengthening integral ribs 25 at the sides. The forward portion of the socket at the lower edge is cut away and p resents shoulders 26. A substantially v tical shaft 27 has thc upper end rigidly mounted in the opening 24 of the socket and has the lower end formed into a laterally-disposed arm 2S. A sleeve 29 is arranged upon the sl1al`t27 and is free to rotate thereupon. The sleeve 29, near the upper end, has a laterally-extending arm 30 and similarly, at the lower end, has a laterallyextending arm 31, shorter than the arm 30. The arm 30 has an integral stop 32 for a purpose which will appear hereinafter.

racket 33, having a suit-ably formed recess 34, is pivotally arranged upon the arm 2S ofthe shaft 27, the sleeve. 29 seating against the upper end of the bracket 33, which has at the lower side. lateral extensions 35. The. arm 28 extends through the opening of the. bracket and is secured in posit-ion by means of a transversr pin 36. At the under side the bracket 33 has a rounded recess 37 which seats upon a transverse shaft 38, and upon which it is secured by means of bolts 39 arranged in suitable openings in the shaft 38 and the bracket 33. The upper face. of the socket 21 is suitably inclined to permit the stub tongue 1 to rest evenly thereupon as is shown most clearly in Fig. 4-

The extremities of thc transverse shaft 38 are upwardly disposed and constitute pivot pins 40, u on which are rotatably mounted axles 41, aving suitable vertical openings for the purpose. The axles 4l carry whee s 42 having hubs 43 and peripheral lianges 44. The urpose of the flanges is to permit the whees to gri more firmly in soft ground such as that ol a plowed field, and to irevent sidel movement of the wheels. The hubs 43 extend beyond the wheels at one side, and the spokes 45 of the wheels are inclined Ytowards the extending ends of the hubs to permit the wheels to be set as close possible to the pins 40. The axles have-collars 46 arranged upon the pins and are secured in position by transverse sto i pins 47. The axles further have forwardly extending integral arms 48 having openings. The arms 48 are operatively connected by means of links 49 with the arrn 31 of the sleeve 29. The links having the ends laterally and op ositely disposed are pivotally arranged in t e. openings of the arms 4S and in similar o eningsof the arm 31. The. ends of the lin.:s which are pivoted upon the arm 31 are secured in posi' tion by means of transverse pins 50.

An eye-bolt 51 is carried by the guiding tongue 18, and operatively connected by means of a link 52 having eyes 53 and 54, with the arm 30 ofthe sleeve 29. The. arm 30 has a suitable o ening 55, at the end of. which is arranged t 1e eye 54 of the link 52; the eye 53 of the latter being mounted at the eye of the eye-bolt 51. The arrangement is such, that the distance between the pivotal point of attachment of the guiding tongue and the point of attachment of th linx 52 atv the tongue 18, is greater than thc length of the arm 30, so that when the guiding tongue is'laterally displaced through a certain angle, the arm 30 'a'.ll be displaced in the same direction, but through a greater angle, owing to its shorter le"gt.h. It will be understood that as the arm 30 is moved to one side or the other, the arms of the axles are similarly dislaced through the connecting -arms and inks, the. arrangement being such that the wheels are moved through an angle considerably greater than the angle through which the guiding tongue is n'aoved. The movement of the arm 30 is limited by the shoulders 2G of the socket, the stop 32 of the arm 30 engaging the shoulders to limit tbe movement. The socket rests upon the stop and the u per ind of the sleeve as is'sbown most lear y in The tractive power 1s applied at the end of Cil means of a chain 6b sind a bolt 05 more efT- l cicntly to apply the tructive power. When the trat-tive tower is supplied by draft ani l mals. the pull is exerted upon the end oi the member l und so transmitted to the vehicle. The animals nearest to the tongue `l\` are secured tlxeretoin such a manner. that when the drivcr desires to guide the machine to one side or the other tht` movement the animals in that direction will correspondingly turn the tongue in thc same direction. 'lhe lateral movement oi the tongue is transmit ted through the connecting linlis to the wheels which travel along the ground, und in consequence of thc lateral`movement of the tongue theu'heels ure partly rotated al: iut a vertical axis. ily thus laterally disposing the guide wheels, the direction ol' the movement of the entire vehicle is quickly and easily nltercd. This is especially true il th ground is heavy and the tlunges ol the wheels are sunk into it somewhat*` for in this ease there is absoluteiy no skidding or lateral sliding of the wheels.

I prefer to provide. my device with a truck and two guide wheels: if :so desired. however. the truck' may be dispensed with and a single guide 'wheel employed as is shown in Fig, ln this caso the guide wheel has a peripheral flange 65 :it the cent-er of its rim und is rotatably mounted l'ietwccn the sides of the fork 5t). The slccve tr in this casehas but one lateral arm nl to which is secured the connecting link 512, joining itwith the tongue 1H; the sleeve is rigid with the shaft 62 which is pivotally mounted in the socket 63. Thus the lateral displace-i ment of the tongue 1.'\` is transmitted directly to the single wheel 54 through the-connetting link Itis of advantage to have thc tongue truck hinged to the vehicle. in the case of a harl vester, for instance, as it is necessary to l permitthc harvester to be tilted intro ddl'crent positions in harvesting grain of various lengths.
